SHUBAEL COTTLE, OF NEW YORK, N. Y.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 391,230, dated October16, 1888.

Application tiled November 21, 1887. Serial No. 255,708.

To all whom t may concern:

Be it known that I, SHUBAEL COTTLE, of the city, county,and State of NewYork, have invented a new and useful Improvement in Stud, Collar, andSleeve Buttons, of which the following is a specification.

My invention relates to a stud, collar, or sleeve button of novelconstruction, the distinctive features of which are a hollow head andhollow post and a solid back, the whole being produced from sheetmetal,so that no opening is left into the interior of the button.

The object of my invention is to simplify the construction of thebutton, to render the same stronger and more durable, to give the buttona uniformly smooth exterior, and to do away with any openings in whichdirt may collect.

In the accompanying drawings, Figure l is a vertical section of my newbutton on the line a: x of Fig. 2, and Fig. 2 is a plan view.

Similar letters of reference indicate like parts.

A is the head of the button, made of sheet metal and hollow.

B is the shank or post, also hollow and made of sheet metal.

C is the base or back, which is solid metal, and which therefore formssubstantially a flange around the closed lower end of the hollow post.

In the embodiment of my invention here illustrated I show the hollowhead, hollowV shank, and solid back formed of asingle piece of metal,and this construction I consider preferable.

I produce my aforesaid button preferably in the following manner: Itirst make a tube of thin metal, having at one end a solid body ofmetal, which closes said end, the other end of the tube being open. Ithen compress the middle portion of this tube in suitable dies to (Nomodel.)

produce the shank or post B, and then Hatten or draw out the solidportion to produce the solid base or back C. The head A then is open atthe top. This opening I close by adjusting the button in a lathe, and bymea-ns of a suitable spinning-tool spinning in the circumferential edgeof the opening until the aperture is entirely closed by the metalmeeting, when the upper surface of the head A is finally smoothed off,thus completing the construction ofthe button.

In another application for Letters Patent filed December 9, 1887, SerialNo. 257,385. I have fully described and claimed my aforesaid process,which is therefore herein disclaimed.

I claiml. A stud, collar, or sleeve button consisting of a single pieceof thin metal without an opening into its interior, and having a solidback and a hollow post and head, substantially as described.

2. A stud, collar, or sleeve button having a hollow post and head,consisting integrally of a continuous closed metallic shell and a backformed of a flange of solid metal surrounding the lower part of saidpost, substantially as described. y

3. A stud, collar, or sleeve button having a hollow post and head,consisting integrally of a continuous closed metallic shell and a backintegrally formed of a single thickness of said shell, substantially asdescribed.

4. A stud, collar, or sleeve button of thin met-al, having a hollowhead, a hollow post closed at its lower end,and a flange at the lowerpart of said post integral therewith and of a single thickness of saidthin metal, substantially as described. SHUBAEL CO'ITLE.
